IMPROVEMENT IN HUBS.

Specification forming part of Letters Patent No. 168,445, dated October5, 1875; application filed J nly 3, 1875.

To all whom it may concern:

Be it known that I, LEVI N. BEWLEY, of Gorning, in the county of Steubenand State of New York, have invented a new and valuable Improvement inHub-Bands; and I do hereby declare that the following is afull, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a longitudinal centralsection of my hub and axle, and Fig. 2 is a plan view of my hub withcaps removed.

This invention has relation to improvements in hubs.

The object of the invention is to provide a means whereby the band uponeach end of the hub may be secured in place and prevented from rattling.To this end the nature of my invention consists in a metallic bandshrunken on each end of a wooden hub, which band is made screw-threaded,in combination with a cap, which is adapted to be screwed upon theprojecting end of the box and upon the aforesaid band, whereby a verysecure attachment of the caps and hub is obtained, which will be proofagainst rattling, and the necessity ofbushing the axle-box is done awaywith, as will be hereinafter more fully explained.

In the annexed drawings, A designates a tapering axlearm of the usualwell-known form and construction, which is provided, near its point ofunion with the body of the axle, with a collar, a. This collar isdesigned to be received into an enlargement of corresponding form in theend of an axle-box, B, which fits snugly in a wooden hub, C, and ofwhich the two screw-threaded ends 0 0 project slightly outward beyondthe vertical faces of the hub, as shown in Fig. 1. At each end of thehub an annular rabbet, b, is formed, upon which are shrunken strongmetallic bands D D the exterior surfaces of which are male-screwthreaded, as shown at d, Fig. 1, for a purpose hereinafter explained.

E E represent caps, of any suitable metal, the former of which isdesigned to be secured upon the inner, and the latter upon the outer,end of the said hub. Cap E has a femalescrew threaded neck, 6, adaptedto be applied upon the projecting screw-threaded end 0 of the axle-box,and an enlarged neck, 6, also similarly screw-threaded, which isdesigned to be applied on the shrunken band D on the inner end of thehub. Gap E has also two necks, f f, both of which are female-screwthreaded, and are designed to be applied upon the projecting end of thesaid box and the band. It has also an annular guard, g, designed toprotect the holding-nut D which is applied upon the end of the spindlefor the purpose of preventing the samefrom being drawn through the boxand allowing the wheel to leave the axle.

Caps E E being applied upon their respective ends of the hub, and theirfemale-screw threaded necks e c and ff being applied, respectively, uponthe ends of the axlebox and upon bands D D, which are immovable upon thesaid hub, a very safe, strong, and reliable attachment of the caps tothe hubs will have been obtained, and any rotation of the said boxindependent of the hub will be efi'ectually prevented.

By this means the necessity of wedging or bushing the axle-box, as it ismore commonly called, is done away with, and the hub, being maintainedin its integrity, is allowed to preserve its full strength, therebygreatly increasing its durability and power of resistance to strain.

What I claim as new, and desire to secure by Letters Patent, is-

1. The cap E, having screw threaded necks ff, in combination with thewooden hub O,

having screw-threaded band D and the axlebox B, having screw-threadedend a, substantially as and for the purpose set forth.

2. The caps E E, having screw-threaded necks a e f f, the wooden hub 0,having screw-threaded bands D D, and the axle-box B, havingscrew-threaded ends 0 0, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
